LO ADING-MACHINE Specification of Letters Patent.

Patented Dec. 31, 1907.

Application filed July 22. 1907- Serial No. 384.987-

To all whom it may concern:

Be it known that I, THOMAS N. CARTER, a citizen of the United States, residing at Norton, in the county of WVise and State of Virginia, have invented certain new and useful in Loadi11gl\/Iacl1ines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to loading machines designed especially for handling stone in railway cuts or quarries and loading the same onto cars, and has for one of its objects to provide a comparatively simple inexpensive device of this character which may be readily transported from place to place, and set up for use; one by means of which the stone or other material to be lifted may be quickly hoisted and brought to proper position over the car, and one wherein the carriage embodied in the device Will move automatically by gravityin one direction and may be quickly and positively moved in the other direction in. the operation of depositing the material.

With these and other objects in view, the invention consists of certain novel features of construction, combination and arrangement of parts as will be more fully described and particularly pointed out in the appended claims.

In the accompanying drawings, Figure 1 is a side elevation of a hoisting and loading ma chine embodying the invention; Fig. 2 is a top plan view of the same; Fig. 3 is a vertical longitudinal sectional view on the line 33 of Fig. 2; and Fig. 4 is a front end elevation of the machine.

Referring to the drawings, it will be seen that the machine embodies in its organization a frame comprising vertical posts or standards, 1, rising from base pieces, or runners, 2, in which are journaled wheels, 3, adapted for travel upon the rails, 4, of a suitable track, there being attached to the standards 1, at points above and suitably remote from the base pieces 2, longitudinal side bars, 5, connected by spaced cross bars, 6, while suspended at the upper ends of the standards 1, which are connected by cross braces, 7, are transverse shafts, 8, having grooved guide pulleys, 9, rotatably mounted thereon.

Attached respectively to the inner faces of the standards 1 is a pair of downwardly and forwardly inclined guide rails, 10, having upturned terminals, 11, and on which there is at the same arranged for travel a carriage, 12, movable longitudinally of the frame and having wheels, 13, which travel on the rails, 10, there being included in the carriage, 12, a cross rail, 14, and a cross rod, 15, on which is journaled a grooved guide pulley, 16.

Disposed at the rear of the machine and attached to the cross bars 6, is a pair of spaced vertical bearing plates, 17, having suitable bearings, in which is journaled a hoisting shaft, 18, carrying a hoisting drum, 19, and equipped at one end with a belt pulley, 20, and at its other end with a crank portion, 21, there being also journaled in suitable bearings in the plates 17, and at a point in ad vance of the hoisting shaft, a carriage-operating shaft, 22, carrying a drum, -23, and provided at one end with a crank handle, 24, while connecting the forward ends of the guide rails, 10, is a rod, 25, having a guide pulley, 26, rotatably mounted thereon.

Attached at one end to the front axle of the carriage, 12, and at its other end to the rear axle thereof, is a carriage-Operating cable, 27, which is led over the guide pulleys 26 and 9, and wound at a point between its ends twice around the drum, 23, while wound upon the drum 19 is a hoisting cable, 28, arranged. for travel between its ends over the guide pulley, 16, and having its front end threaded. through a pulley block, 29, sus pended by a yoke, 30, from the axle, 31, of a shifting pulley, 32, arranged for travel on a cross rail, 14, the cable 28 being terminally engaged with a pulley block, 33, carrying a pair of grappling members, or hooks, 34, by means of which the material is grappled and hoisted above the car, ted lines in Fig. 1, and which, in practice, runs to a position beneath the frame of the machine.

In practice during the operation of loading the stone or other material onto the car, the carriage-operating shaft, 22, is rotated in the proper direction for permitting the carriage, 12, to run automatically by gravity downwardly to the forward end of the machine upon the inclined rails, 10, the shaft 18 being thereafter operated to permit the pulley block 33 to descend in position for the grappling members, 34, to be engaged with the material. After the material has been grappled, the hoisting shaft, 18, is rotated for winding the cable 28 thereon and lifting the pulley block, 33, together with its load, while, time, the shaft, 22,;1is manipu- 35, indicated by dotlated for positively moving the carriage, 12, j

, sustained for rotation in rear of the guide rearwardly on the rails, 10, thus to properly position the carriage above the car prior to depositing the material thereon, it being noted in this connection that owing to the provision of the shifting pulley, 32, which travels on the guide rail, 14, the grappling members, 34, may be moved back and forth transversely of the car for depositing the load at one side or the other of the latter.

The various parts of the frame of the machine are detachably connected by means of removable bolts, whereby the machine may be taken apart for transportation and thereafter readily set up for use, and, further, that when in operation, the machine may, owing to the provision of the rollers, 3, be readily shifted back and forth along the rails, 4, to bring the carriage, 12, in proper posi tion over the several cars of a train to be loaded. w v

Having thus fully described my invention, what Iclaim as new, and desire to secure by Letters-Patent, is: l

1. In a hoisting and loading machine, a frame equipped with trans orting wheels, a pair of guide rails connecte therein, a carriage arranged for travel on said rails, a drum rails, a carriage operating cable wound between its ends on the drum and terminally engaged w1th the front and rear portions of the carriage, a hoisting cable connected for movement with the carriage, and a hoisting drum for o crating said cable.

2. In a oisting and loading machine, a frame equipped with transporting wheels, a pair of downwardly and forwardly inclined guide rails connected therein, a load-shifting carriage arranged for travel on said rails, said carriage being adapted for movement automatically by gravity in one direction, and means for positively moving the carriage in the reverse direction.

3. In a hoisting and loading machine, a frame, a pair of inclined rails connected therein, a load-shifting carriage arranged for travel on said rails and provided with a cross rail, a shifting roller arranged for travel on said cross rail in a direction transversely of the carriage, a yoke depending from said roller, a load-hoisting device suspended from the yoke, means for operating said hoisting device, and means for positively moving the carriage in one direction on the rail, the carriage being adapted for automatic travel by gravity in a reverse direction.

In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.
